You'll find everything from short meetings to long dates, massage, and also offers with closer treatment, along the lines of the girlfriend experience. Some escorts also offer companionship for nights out beyond the neighborhood. What's published in the ad is what's respected, and asking about anything different before arranging is the right move.
As for the venue, alongside those who host at home there are others who work with home visits: they travel to the northern and eastern neighborhoods or to a hotel in more central areas. Settling the format in the first message is what saves the most time, especially if the trip means crossing half the city.
Contact is made directly on WhatsApp with the person in the ad, with no middlemen and no third-party diary. A specific message, with day, time slot and duration, is enough to close it. And if the profile posts working hours, respecting them comes first: writing outside that window is the quickest way to get no reply at all.
The neighborhood's density works in favor of discretion. On streets with plenty of people living, coming and going at all hours, a new face is news to nobody and a visit disappears into the normal movement of the day. It's the kind of anonymity that populated areas give and that small neighborhoods, however quiet, cannot offer.
